Application of Central Tendency (Video)

Using the TI-83/84:
Enter data:

1. STAT --> 1:Edit...
   
2. Enter data in a list
   
3. STAT --> 2:SortA(
   
4. Enter your list: 2ND --> 1 for L1, 2ND --> 2 for L2, etc.
   
5. STAT --> 1:Edit... to view sorted data
   

Find mean and median:

1. Make sure data is in your list
2. 2ND --> STAT --> MATH --> 3:mean( or 4:median( and enter your list
   
   
   

Lesson 27: Stem-and-Leaf and Box-and-Whisker Plots

EQ: How do you create and utilize stem-and-leaf and box-and-whisker plots?

Box-and-Whisker Plots

Entering and Sorting Data

1. Enter the data in a list
2. 2nd --> Stat Plot
   
3. Choose a plot and adjust
   
4. Zoom --> ZoomStat
   
5. Examine the graph
   
6. Trace
   

Lesson 28: Scatterplots and Lines of Best Fit

EQ: How do you use a scatterplot to predict possible outcomes of a situation?

Scatterplots and lines of best fit

Scatterplots in the TI83/84:

1. Enter the data: Stat --> 1:Edit...
   
2. L1 = Independent, L2 = Dependent
   
3. 2nd, Y= --> 1:Plot1...
   
4. Turn on --> Choose scatterplot --> Xlist is independent, Ylist is dependent --> Choose a mark
   
5. Zoom --> 9:ZoomStat
   
   
6. Stat --> Calc --> 4:LinReg(ax+b)
   
7. LinReg(ax+b) L1,L2,Y1
   
   
   
   To get Y1: Vars --> 1:Function --> 1:Y1
   
   
   
8. Graph
   

Make sure the Diagnostic is on to see the coefficient of correlation: 2nd, 0 --> DiagnosticOn
